  2. Raise the engine in order to remove the weight from the mounts and in order to place a slight tension on the rubber. Observe both mounts while raising the engine.
  3. Replace a powertrain mount if it exhibits one of the following conditions:
  4. • Hard rubber surface covered with heat cracks
    • Rubber separated from the metal plate of the mount
    • Rubber split through the center
    • Fluid leaking from hydraulic mounts
